cocomon

A local command center for your Claude Code sessions.

Install

pip install cocomon

Usage

cocomon

Opens at localhost:6300. cocomon reads from ~/.claude/projects/, where Claude Code stores conversation JSONL files.

Open from your phone

Run cocomon on your computer and expose it to your local network:

cocomon --host 0.0.0.0

cocomon prints a LAN URL, and each session page includes a QR code you can scan from your phone. Your phone must be on the same network as your computer.

Options

cocomon --port 8080                  # custom port
cocomon --host 0.0.0.0              # expose on LAN
cocomon --projects-path /other/path  # custom Claude projects dir
cocomon --no-statusline              # skip Claude statusline integration
cocomon --statusline-base-url URL    # custom URL shown in Claude's statusline

Features

Session console -- All your Claude Code projects and sessions in a sidebar, sorted by recency. Open old conversations or jump into active sessions.

Full-text search -- Search across every session. Filter by project, role, date range, or content type (code, errors, tool use, file edits).

Syntax highlighting -- Code blocks render with language detection and proper highlighting via Pygments.

Diff inspector -- File edits from Claude's Edit tool display as green/red line diffs, so you can see exactly what changed.

Live session control -- If Claude Code is running in a supported terminal, cocomon detects the session, shows its live status, and lets you send messages directly from the browser. Works with iTerm2, Terminal.app, and cmux.

Phone control over LAN -- Start cocomon with --host 0.0.0.0, scan the session QR code, and continue from your phone while Claude Code runs on your computer.

Dark / light theme -- Toggle in the top-right corner. Preference is saved.

QR code sharing -- Each session gets a QR code link for quick access from your phone over LAN.

Mobile responsive -- Works on phones and tablets.

Security

cocomon is local-first. By default it binds to 127.0.0.1, so only your computer can access it.

Use --host 0.0.0.0 only on a network you trust. That makes cocomon reachable from other devices on your LAN, including session history and any live-session send controls. Do not expose cocomon directly to the public internet.

How this differs from Claude Code Remote Control

Claude Code Remote Control is the official remote-control experience for Claude Code.

cocomon is a local-first session console focused on your Claude Code work: fast history search, readable transcripts, syntax-highlighted code, diff inspection, LAN sharing, and browser-based control for live terminal sessions.

How it works

Claude Code stores every conversation as a JSONL file in ~/.claude/projects/<project-hash>/. Each line is a JSON object representing a message, tool call, or tool result.

cocomon parses these files, indexes them for search, and serves a web UI with FastAPI.

Development

git clone https://github.com/gdagitrep/claude-code-viewer.git
cd claude-code-viewer
pip install -e .
cocomon

The server auto-reloads on file changes during development.

Requirements

• Python 3.8+
• Claude Code (to generate conversation history)
